Printable Arm Diagrams

Help yourself to learn the anatomy of the arm by following these free and printable anatomy diagrams! These printable diagrams are designed to guide you in studying the structure and anatomy of arm. The arm is the part of the upper limb between the shoulder joint and the elbow joint. The muscles of the arm and hand are specifically designed to meet the body’s diverse needs of strength, speed, and precision while completing many complex daily tasks. Therefore, it is important to study the anatomy of our arm. Follow our collections of arm diagrams to know more about the arm anatomy.

The arm diagram above shows the anatomy of the forearm muscles. The muscles of the upper arm are responsible for the flexion and extension of the forearm at the elbow joint. Flexion of the forearm is achieved by a group of three muscles: the brachialis, biceps brachii, and brachioradialis. These flexor muscles are all located on the anterior side of the upper arm and extend from the humerus and scapula to the ulna and radius of the forearm. Additionally, the biceps brachii operates as a supinator of the forearm by rotating the radius and moving the palm of the hand anteriorly. On the posterior side of the upper arm is the triceps brachii, which acts as an extensor of the forearm at the elbow and the humerus at the shoulder. The triceps brachii, as its name indicates, has three heads whose origins are on the scapula and humerus. These three heads merge to insert on the olecranon of the ulna.

The bones of the arm and hand have the important jobs of supporting the upper limb and providing attachment points for the muscles that move the upper limb. Consisting of the clavicle (collar bone) and scapula (shoulder blade), the pectoral girdle forms the attachment point between the arm and the chest. The clavicle is a long bone that connects the scapula to the sternum (breast bone) of the chest. It permits the shoulder joint to move in circles while remaining attached to the bones of the chest. Posterior to the clavicle is the scapula, a flat, triangular bone located lateral to the thoracic spine in the dorsal region of the body.
